ANCHORING- DEVICE.

Application filed December 10, 1923'. Serial No. 679,807.

To all whom it may concern:

Be it known that I, RALPH S. PEIRcE,

- citizen of the United States, residing at Hinsdale, in the county of Du Page and State of Illinois, have invented a certain new and useful Improvement in Anchoring Devices, of which the following is a full, clear, concise, and exact description.

My invention relates to anchoring devices of the class employing expanding elements and elements of softer material expansible thereby. The invention has for its general object the provision of a second expanding elementwhic-h operates as a tool in conjunction with the first for expanding the expansible element and which has an improved assemblage with either and preferably both of the other elements whereby it is constantly in position to be used as a tool for this intended purpose.

In accordance with'one characteristic ofthe invention, the second expanding element or tool is initially and permanently assembled with the expansible element. In accordance with another characteristic of the invention, the second expanding element or tool and the first expanding. elementare provided with interengaging formations which positively efi'ect the initial assemblage of the two expanding elements without relying upon friction for this purpose.

In the preferred embodiment of the invention the second expanding element or tool is assembled with both of the other elements of the anchoring device in a manner to maintain all of them together as a unit ready for installation when desired.

The invention will be more fully explained with reference to the accompanying drawing showing the preferred embodiment thereof and in which Fig. 1 is an axial sectional view illustrating the anchoring device inserted in place and in readiness to be adjusted by the expanding tool element there of; Fig. 2 is a View similar to Fig. 1 but showing the anchoring device adjusted in a holding position and illustrating an object held thereby; Fig. 3 is a view similar to Fig. 2 with the exception that the expanding tool element of the device is shown in elevation; Fig. 4 is a view illustrating the parts havin the relation shown in Fig 1 the two expan g elements being shown in elevation and the expansible elements bein shown in section; and Fig. 5 is a sectiona view on line 5-5 of Fig. 3.

in the nut.

Like parts are indicated by similar characters'of reference throughout the different figures.

The expanding element 1 is shown in the form of a tapering or conical nut which is to be held in position within a wall or other support to receive a bolt 3 employed for any purpose, such as, the mounting of a clothes hook 1. The expansible element 5-is employed for maintaining fixed assemblage of the nut 1 andthe support 2. This expansible element is desirably formed with a bore tapering similarly to the nut 1 which is received in this bore. These two elements are maintained in permanent assemblage. prior to use, by means of an internal rib (1 formed upon and within the expansible element- 5 and entering the annular groove 7 The expansible element is desirably formed of lead and the annular rib 6 is produced by advancing the expansible element under pressure and squeezing it to cause the metal to flow into the groove. The expanding tool 8 which is employed in cooperation with the expanding element 1 to expand the expansible element 5 is caused to be a component part of the anchoring device hy being assembled with either, and preferably both, of its complemental elements.

In the preferred embodiment of the invention the expanding tool is in the form of a flanged hollow cylinder 8 that has a series of lon itudinal slots 9 formed along and through t e same. This cylinder is referably roughened at its inner end as lndicated at 10 to have holding engagement with the outer end of the expansible element 5 that is placed thereover. The assembly of the expanding tool 8 with the balance of the anchoring device is desirably further assured by providing a positive initial interengagement of the two expanding elements without depending upon friction. This interengagement is desirably effected by providing lugs 11 upon the inner sides ot the fingers formed out of the cylinder 8 by the slots 9 and by forming another annular groove 12 in the nut 1 which receives these lugs that are sprung into the same when the cylinder is moved sufiicientl inward to bring the lugs into thezone 0 this groove.

The ex ansible element 5 desirably extends to t e rear end of the expanding element 1, the expanding tool 8 being forced pandin by means of hammer blows upon its flange 8 or otherwise, further between the expanding element 1 and the expansible element 5 to spread the latter laterally to have the desired gripping engagement with the support 2. In the final portion of the inward movement of the expanding element 8 its flange 8 compresses the expansible element 5 in an axial direction to cause further lateral spreading movement thereof and to prevent its exudance forwardly. It will be seen that the expanding element 1 performs its function through the intermediation of and in cooperation with the expanding element 8, which itself is expanded by the expanding element 1. To prevent the expanding element 1 from turning with respect to the parts surrounding it, I form it with roughened portions 13 which grip the inner end of'the expanding element 8. The roughened portions 10 upon the expanding element 8 engage the inner end of the expansible element 5 further to guard against the turning of any of the elements of the anchoring device with respect to the support 2 receiving the same. a

It is obvious that changes may be made without departing from the spirit of my invention. a
